This bike has better vibes than Mr.Café "washed out" . A mag wheel GS1000 is a far better handling and safe bike than a spoked wheel one. I'd offer 450USD. Where are all the stock parts?, ask him.
Anyone who is so broke that a 40mpg bike is a too costly to ride to work is unlikely to have maintained it properly and used quality oil and parts. It's like a free ticket to a poverty theme park, and then they lock the gates.
